DyLight 650

DyLight™ 650 (Ex-Max 652 nm/Em-Max 672 nm)

DyLight™ 650 is a red-emitting fluorophore that excited by the 640 nm laser and collected using a 670/30 nm bandpass filter. DyLight™ 650 has an excitation peak at 652 nm and an emission peak at 672 nm, and is spectrally similar to Alexa Fluor™ 647 and Cy5. DyLight™ 650 is most commonly used in flow cytometery and fluorescence microscopy applications.
